Why did the cost of Recount 2016 increase?

On November 28, the state of Wisconsin announced the final estimate for the recount filing fee is $3.5 million—an outrageous cost increase from the initial estimate of $1.1 million state elections officials gave us based on the last statewide recount. Thanks to over 161,000 small-dollar donors like you, we had enough money in hand to pay this fee and move forward with the recount.
We stand by our commitment to verify that the vote in Wisconsin was accurate and secure, and this exorbitant cost did not deter us. We are committed to ensuring that a secure vote should not come at such an unconscionable cost. As citizens in a democracy, it should be our right.
